Product details
Overview
MAX6025AEUR-T from Analog Devices is a precision, low-dropout, micropower series-mode voltage reference delivering 2.500V ±0.2% initial accuracy in a 3-pin SOT23-3 package. It features <15ppm/°C temperature coefficient, 100mV dropout at 500μA load, and operates from (VOUT + 0.2V) to 12.6V input. It serves as a stable reference for ADCs, DACs, and sensor signal conditioning in battery-powered instrumentation.
For engineers reviewing the MAX6025AEUR-T datasheet, MAX6025AEUR-T pinout, MAX6025AEUR-T application, or MAX6025AEUR-T equivalent, this page delivers verified electrical specifications, thermal stability data, load regulation performance, and real-world design context for low-power, space-constrained systems requiring high-accuracy voltage references.
Technical Context
The MAX6025AEUR-T employs a proprietary curvature-correction circuit and laser-trimmed thin-film resistors to achieve <15ppm/°C tempco over –40°C to +85°C and 0.2% initial accuracy. Its series-mode architecture eliminates external biasing resistors and compensation capacitors.
It draws only 27–35μA quiescent current with just 0.8μA/V variation across input voltage, sinks or sources ±500μA, and remains stable with 0–2.2nF load capacitance - enabling direct integration into compact, low-noise analog front-ends without layout overhead.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.500V ±0.2% (±5mV) at +25°C - enables 12-bit+ system accuracy without calibration |
| Tempco | <15ppm/°C (–40°C to +85°C) - drift ≤ ±3mV over full range, critical for industrial sensors |
| Dropout Voltage | 100mV at 500μA load - supports operation down to 2.6V supply in 2.7V systems |
| Quiescent Current | 27–35μA - extends battery life in multidecade portable devices |
| Load Regulation | 0.14μV/μA sourcing - output shift <70μV across full ±500μA load swing |
| Line Regulation | 15μV/V - negligible output change over input variations in noisy power rails |
| Capacitive Load Stability | 0–2.2nF - no external capacitor required, saving PCB area in wearables and IoT nodes |
Pinout & Package
MAX6025AEUR-T uses a standard 3-pin SOT23-3 package (JEDEC TO-236AB), with 1.0mm nominal body height, 2.92mm × 1.30mm footprint, and gull-wing leads. Pin 1 is IN, Pin 2 is OUT, Pin 3 is GND - confirmed by official Analog Devices pin configuration diagram and top-mark "FZAQ".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Supply Voltage Input | Accepts 2.7V–12.6V; must exceed VOUT + 200mV for regulation; withstands –0.3V to +13.5V absolute max |
| 2 (OUT) | Reference Voltage Output | Delivers 2.500V ±5mV; capable of sourcing/sinking ±500μA; short-circuit protected to GND or IN |
| 3 (GND) | Ground Reference | Return path for internal bandgap core and output stage; requires low-impedance connection for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| No external compensation capacitor required | Reduces BOM count and PCB area; stable up to 2.2nF load capacitance without oscillation risk |
| Supply-current independence from VIN | Only 0.8μA/V variation ensures predictable battery drain across wide input voltage swings |
| Low 100mV dropout at full 500μA load | Enables use in 2.7V single-cell Li-ion or coin-cell systems where headroom is constrained |
| 130ppm temperature hysteresis | Ensures repeatable reference value after thermal cycling - vital for recalibration-free field instruments |
| 0.1% turn-on settling in 85μs (COUT = 50pF) | Supports fast-sampling data acquisition systems without reference-related timing delays |

FAQ
What is the maximum load current the MAX6025AEUR-T can source or sink?
The MAX6025AEUR-T can source or sink up to ±500μA while maintaining regulation and specified accuracy. This capability supports driving ADC reference inputs, op-amp bias networks, and small DAC loads directly without buffering - verified across –40°C to +85°C per Electrical Characteristics table on page 3 of the Analog Devices datasheet.
Does the MAX6025AEUR-T require an external output capacitor for stability?
No, the MAX6025AEUR-T is internally compensated and stable with 0–2.2nF output capacitance - no external capacitor is required. This eliminates a common BOM item and saves PCB area, especially valuable in wearables and miniaturized IoT sensors where board space is at a premium.
What is the minimum input voltage required for the MAX6025AEUR-T to regulate properly?
The MAX6025AEUR-T requires VIN ≥ (VOUT + 0.2V) = 2.7V to maintain regulation at full load. At 500μA output current, dropout is guaranteed ≤200mV, meaning 2.7V input sustains 2.500V output - enabling reliable operation in 2.7V–3.3V battery-powered systems.
How does the MAX6025AEUR-T compare to shunt-mode references in terms of supply efficiency?
Unlike shunt-mode references that waste current through a series resistor, the MAX6025AEUR-T draws only 27–35μA quiescent current - independent of load - reducing total system power by >90% in standby. Its supply current varies just 0.8μA/V, eliminating inefficiency penalties across varying input voltages.
Is the MAX6025AEUR-T RoHS-compliant and lead-free?
Yes, the "+T" suffix in MAX6025AEUR-T indicates RoHS-compliant, lead-free packaging per Analog Devices' specification. The device meets JEDEC J-STD-020 moisture sensitivity level 1 and is qualified for reflow soldering per IPC/JEDEC J-STD-020 standards.
